The slider 3 has an annular space 6, 7 formed by a gap between the guide flanges 4, 5, and a control flange 8. A plurality of control holes 9, 10 radially passing through the housing in the region of the control flange 8;
11 , the control holes communicate with each other in the circumferential direction in the region of the inner peripheral surface of the housing 2 and form an annular space 40 around the slider 3 . The control valve 1 is connected via an annular space 40 and a control line, for example to a hydraulic motor, and in the region of the annular space 6 an inlet hole 12 formed by a radial through hole connects the control valve 1 to an annular space, not shown in detail. The control valve 1 is connected via an inflow line to a pressure fluid storage tank and a backflow hole 13, which is constituted by a radial through hole in the area of the annular space 7, allows the pressure fluid to flow through the annular space and a backflow line, not shown in detail. Connect to a storage tank, for example a hydraulic motor. A certain number of control holes can be chosen arbitrarily depending on the flow requirements and cooperate with the control edges 14, 15 of the control flange 8. The annular space 40 has control holes 9, 1 which intersect in the area of the inner circumferential surface 36 of the housing 2.
0,11. An electromagnetic control device 18 is provided in the recess 17 in one end region of the housing. This control device allows the slider 3 to move axially against the force of the compression spring 19. The control device 18 has a winding form 2 made of a medium that repels water and oil.
1, and a spacer ring 23 made of a non-magnetic material that abuts against the guide flange 5 in the axial direction on the pedestal 22 at one end of the slider 3, and a centering bush made of the same non-magnetic material. 24 and a retainer 25 attached between the two.
The former 21 is supported on a magnetic core 26 of soft iron.
Back side 2 facing the spacer ring 23 of the magnetic core 26
In the axial blind hole 28 of 7 is a self-cutting hexagonal internal thread 29. The screw 29 is provided with a preferably conical recess 30 in an internal hexagonal area in which it supports the compression spring 19 abutted against the centering bush 24. The slider 3 is provided with an axially penetrating leakage line 31 which leaks through an axially penetrating leakage line 34 in the centering bushing 24, inter alia through a leakage space 32 which is limited by the housing mounting 33 shown in phantom. The backflow hole 13 is connected to the space 35 and passes through a leakage hole 37 configured as a radial through hole in the slider 3.

流体貯蔵タンクへの逆流はしや断される。 When there is no current in the electromagnetic coil 20, the slider 3 is held at the position shown by the compression spring 19,
The annular space 6 is connected to the control holes 9, 1 by means of the control surface 14.
0,11, and the annular space 7 is connected to the control surface 1.
5 communicates with the control holes 9, 10, 11, so that the flow from the inflow hole 12 to the hydraulic motor is interrupted, and the pressure fluid storage from the hydraulic motor via the backflow hole 13 and the control holes 9, 10, 11 is interrupted. Backflow to the tank takes place. When current is supplied to the electromagnetic coil 20, the slider 3 moves in the direction of arrow A against the force of the compression spring 19 via the bushing 24, changing the position of the control surfaces 14, 15 and thus the through-cut. The area is influenced by the pulse width modulated signal.
When the slider 3 is moved in the direction of arrow A to a position where the control surfaces 14, 15 shear the control holes 9, 10, 11 from the inflow hole 12 and the backflow hole 13, respectively, the slider 3 is in its equilibrium position. When the slider 3 moves beyond this equilibrium position further in the direction of the arrow A, the slider 3 has an annular space 6 which communicates with the control holes 9, 10, 11 by means of the control surface 14 and an annular space 7 which communicates with the control surface 15. As a result, the control holes 9, 10, 11 reach a position where they are cut off, so that the pressure flows into the hydraulic motor through the inlet hole 12, and the pressure from the hydraulic motor passes through the backflow hole 13 and the control holes 9, 10, 11. Backflow to the fluid storage tank is immediately cut off.

Due to the displacement action that occurs, the leakage oil flows from the leakage space 32 to the leakage space 35, or vice versa, through the leakage hole 37 of the backflow hole 13 and also to the control holes 9, 10, 11 corresponding to the position of the slider. supply
